In a result just published, astronomers using the NASA/ESA Hubble Space Telescope report the discovery of a ring of dark matter in the cluster ZwCl0024+1652….
The star GJ 436, a diminutive star (red dwarf) 30 light-years from the Sun, was known since 2004 to harbour a 22-Earth mass planet, orbiting 4 million…
On 24 January 2001, Cluster’s spacecraft observed shock reformation in the Earth’s magnetosphere, predicted only in theory, over 20 years ago. Cluster provided…
The way DNA is ‘translated’ into the specific functions of the cell strongly depends on the mechanics, so this information is of great value. Scientists…
More precisely, it refers to how this repulsion influences the spatial and dynamical motion of the electrons. The concept can be likened to the behaviour of…
He described his work at the EPL symposium, “Physics In Our Times” held today (10 May) at the Fondation Del Duca de l’Institut de France, Paris. In particular,…
“As it turns out, the vacuum is not empty – there is a difference between the vacuum and nothingness,” he stated. “Surprisingly, of all known ‘substances’, the…
“Surprisingly, it is very hard to pin down the age of a star”, the lead author of the paper reporting the results, Anna Frebel, explains. “This requires…
They're part of a team that mapped weather on a planet beyond our solar system, a gas giant planet called HD 189733b.”The exoplanet's wind speeds probably…
By studying the behaviour of these atoms and photons in this protected environment, the physicists can illustrate fundamental aspects of quantum theory, such…
The identification of this particular class of explosions gives astronomers a valuable new constraint to help them model and understand stellar explosions. Exploding stars called novae remain a puzzle to astronomers. “Modelling these outbursts is very difficult,” says Wolfgang Pietsch of the Max Planck Institut für Extraterrestrische Physik. Now, ESA’s XMM-Newton and NASA’s Chandra space-borne X-ray observatories have provided valuable information about when individual novae emit X-rays. …
“This was a truly monstrous explosion, a hundred times more energetic than a typical supernova,” said Nathan Smith of the University of California at Berkeley,…
An exploding star first observed last September is the largest and most luminous supernova ever seen, according to University of California, Berkeley,…
The same team of researchers discovered intermediate phases seven years ago in amorphous or disordered materials where networks are covalently bonded. The…
The piece, entitled, “Optimal Control of Quantum Rings by Terahertz Laser Pulses” (1), proposes new annular structures (quantum rings) to define a qbit, i.e….
The south pole of the planet and its gigantic double vortex has been pictured as never before. The south pole of Venus and the double-eyed storm permanently…
